DATE <TIME.H> data validation

Hi guys i have a major problem.

Could someone help me with some data validation input.

Basically i need to be able to input 10 characters usings fgets() not scanf(). And check for a date validation.

So for example

dd/mm/yy it must be in order of date validation.
Could someone please help me

thanks

Well I imagine it would start something like this

Code:

---

#include <stdio.h>

int main ( ) {
  char buff[BUFSIZ];
  if ( fgets( buff, BUFSIZ, stdin ) != NULL ) {
    int y,m,d;
    if ( sscanf( buff, "%d/%d/%d", &d, &m, &y ) == 3 ) {
      /* got 3 ints */
      if ( d >= 1 && d <= 31 ) /* etc etc */
    }
  }
  return 0;
}

Yes, that's what "%d/%d/%d" in sscanf does. It looks for input of the format: int/int/int, so 100/1000/10000 will still get through, but as Salem showed, it can easily be detected by comparing the stored values against a valid range.

cool thanks for what
